  3. Net: add learnable_params_ used by solvers to correctly handle shared… 

    … params

-Params now share diffs as well as data (works due to layers
accumulating gradients into param diffs, rather than overwriting)
-It's now required that any shared params with specified lr_mult's,
decay_mult's match
-TestGradientBasedSolver checks that behavior remains correct with
shared weights
